Re: how to use a customized logging formatter class

[czam...@gmail.com]

As it happens I was looking into this yesterday because my request object includes a couple of attributes that I would like to see listed in the string representation of the request object. 

Your LOGGING settings  needs to have a fomatter entry that looks something like:

'formatters': {

  'my_formatter_name': {

    '()': my_project.module_name.UniqueRequestIdFormatter

  }

}

Make sure to set the formatter attribute of your handler to be the name you gave to your customer formatter. In my example above it would be 'my_formatter_name'. The '()' is a special key which tells the logger that a "Factory" will be used. You can read more about it here: http://docs.python.org/library/logging.config.html#logging-config-dict-userdef

You may also want to look at Custom error reports: https://docs.djangoproject.com/en/1.4/howto/error-reporting/#custom-error-reports (This is what I ended up using instead of a custom formatter)

I have written this custom formatter which inherits from logging.Formatter, how can I configure logging settings so that I can use this for a logger. I see the example in docs where I can update the formatter string but dont know how to link a class to do that.

class UniqueRequestIdFormatter(logging.Formatter):

    def format(self, record):

        record.message = record.msg % record.args

        record.asctime = self.formatTime(record)

        format = u'%s %s %-10s %s +%s %s' % (

        record.levelname,

            record.request.META['REMOTE_ADDR'],

            record.request.user.id if record.request.user.id else record.request.user,

            record.asctime,

            record.request.method,

            record.request.path,

            record.message

            ).encode('utf-8')

        pprint.pprint(record.__dict__)

        return format % record.__dict__
